Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a base station radio frequency test system and test method suitable for an LTE system. Background technique [0002] LTE is one of the mainstream technologies for fourth-generation mobile communications. It supports FDD (Frequency Division Duplex) and TDD (Time Division Duplex) modes. TD-LTE is a time division duplex LTE system, and LTE-FDD is a frequency division duplex LTE system. At present, the commercialization of LTE systems has received the most extensive attention from global operators and equipment vendors. Therefore, the base station equipment is an important network element in the communication network, and its performance determines the quality of the entire system. [0003] In the prior art, the system for the base station radio frequency test of the LTE system is complicated to build, and the manual construction of the test system is easy to introduce unneces...
